Answer to Question #173911 in Physics for anonymous

Question

A stone of weight 50N is completely immersed in a fluid. The weight of the stone shown on the spring balance is 48N. Calculate the volume of the stone

Given the density of fluid is 2100kg/m3

Answer 1

$F_{G0}-F_G-F_B=0\to50-48=\rho Vg\to$

$V=\frac{2}{\rho g}=\frac{2}{2100\cdot9.8}=9.7\cdot10^{-5}\ (m^3)=97\ (cm^3)$ . Answer
